ADC stands for Analog to Digital Converter.
ADC0 on TRK-MPC5606B is a 10-bit ADC.
ADC0_ScanMoode example for MPC5606B (Tested on TRK-MPC5606B Board)
Description:
Converts inputs ANS0, ANS1 and ANS2 using scan mode (continuous).
Reading Analog input (0 to 5V) using ANS0 and Its output is shown using 4 LEDs as below.
Program Outcome:
Analog INPUT => OUTPUT (PB[8]) [LED1 LED2 LED3 LED4] DigitalValue (0-200) => ON OFF OFF OFF DigitalValue (201-500) => ON ON OFF OFF DigitalValue (501-800) => ON ON ON OFF DigitalValue (801-1023) => ON ON ON ON
Problem Statement:Reading Analog input (0 to 5V) using ANS0 and Its output is shown using 4 LEDs as below.
Connections:
LED No. => Port No. => Pad No. => Pin No.(144-pin LQFP package) LED1 => PE[4] => PCR[68] => PIN 132 LED2 => PE[5] => PCR[69] => PIN 133 LED3 => PE[6] => PCR[70] => PIN 139 LED4 => PE[7] => PCR[71] => PIN 140 SIGNAL ADC0_Channel PORT SIU_PAD_CONFIG PACKAGE_PIN (100 144 176) ANS0 => 32 B8 PCR[24]=2000 39 53 R9 ANS1 => 33 B9 PCR[25]=2000 38 52 T9 ANS2 => 34 B10 PCR[26]=2000 40 54 P9
